Xylem 404236 Float & Thermostatic Steam Trap 1-1/2 Inch NPT 125 PSI

The Xylem 404236 is a Hoffman Specialty FT125C Series C float and thermostatic (F&T) steam trap with a 1-1/2 inch NPT connection designed for continuous drainage in low, medium, and high pressure steam systems. Hoffman Specialty is a Xylem brand offering steam and hydronic systems products, with a heritage dating back to 1913.

Key Features:

• Cast iron construction with 125 PSI maximum operating pressure
• Capacity of 4,800 pounds per hour
• Stainless steel internal parts for durability
• Same-side configuration with inlet on top end and condensate discharge outlet on bottom end of cover
• Thermostatic vent allows free passage of air during start-up and closes near saturation temperature
• Removable cover for easy in-line maintenance

Operation: Float and thermostatic traps operate on the density principle, with a thermostatic vent in the top allowing free air passage during start-up. As condensate fills the float chamber, the float rises and through a lever mechanism opens the discharge valve to handle varying condensate loads.

Applications: Ideal for heat exchange equipment requiring quick venting of air and non-condensable gases, modulating pressures with widely varying loads, and systems needing to handle start-up air loads and operate against back pressure. Common uses include heating main drip traps, shell and tube heat exchangers, unit heaters, air handling coils, and steam humidifiers.
